Gumpp & Maier GmbH

What Gumpp & Maier GmbH does

Gumpp & Maier GmbH is a privately held German timber construction company (Holzbau) headquartered in Binswangen, Swabia, Bavaria, founded in 2004 by Alexander Gumpp and Josef Maier. It operates a multi-brand portfolio spanning the timber construction value chain: arstekton serves private customers with custom timber homes, g&m projects addresses business and public-sector clients with complex interdisciplinary projects, modul3 provides timber cutting (Abbund) and prefabricated element manufacturing to peer Holzbau firms, timberC offers wood coating services with environmentally friendly paints, Holzbau-GU acts as a general contractor for turnkey delivery, and Kandlhaus operates as an affiliated brand. The company employs approximately 120-130 staff and self-describes as one of Europe's leading timber construction firms.

The firm's underlying technology combines modern CNC production with traditional carpentry (Zimmerer-Handwerk) craftsmanship, anchored in specialized facilities for timber cutting, element manufacturing, and wood coating. Vertical integration across these steps supports both project economics and the B2B peer offering via modul3. Certifications include FSC/PEFC sustainable forestry compliance, EU Timber Trade Regulation (EUTR) adherence, German Supply Chain Act (LkSG) compliance, and DSGVO data protection. The firm invests in research and development around energy efficiency, CO2 efficiency, and digitalization of timber construction processes.

Go-to-market is direct sales-led through dedicated brand-specific websites and sales teams, serving private customers, commercial enterprises, public-sector clients, and peer Holzbau companies. Revenue is generated via one-time project contracts, general contractor engagements, and B2B sales of prefabricated elements and coating services, with project-based fixed-price offers. The company is independently owned by its founders with no external investors, funding rounds, or M&A activity disclosed.
